I'll say this about keeping puffers. With proper water changes, and a good filter, a tank with a 6x3 footprint, and at least 24" in height will be fine for a MBU IME. However, a 1000 gallon tank wouldn't hurt if you can get one.
Definitely. I wish all my fish could be housed in tanks much larger than they are in, but IMO they're in a healthy environment where they are for now. Although, I don't own a single fish that will ever grow much larger than 12".I'll say this about keeping puffers.
